Description
Technical Field
The invention relates to the technical field of engine fuel injection, in particular to a slow-release air-entrainment injection gas nozzle.
Background
Energy conservation and emission reduction are important ways for realizing the carbon peak reaching and carbon neutralization targets, and in the field of energy and power, the further improvement of the combustion technology in the engine cylinder can effectively reach the double-carbon target in advance. The electric control fuel injection technology, the valve variable technology and the supercharging technology provide infinite possibility for the development of new combustion technology of the engine. The fuel injection technology is the key for developing a combustion system, and determines a technical route and a development scheme of engine development.
Conventional gasoline engines rely on spark plug ignition, while diesel engines typically employ compression ignition, and due to the demands of certain specific areas, two-stroke diesel ignition technology is becoming increasingly important, and the key to determining whether diesel can be ignited is the droplet size distribution of the diesel spray. At present, the injection pressure of direct injection in a diesel engine cylinder is as high as 2200bar, but the minimum droplet diameter is still more than 25 μm, the gas-entrainment injection technology can greatly improve the atomization effect, the minimum droplet diameter can reach less than 10 μ, and the adopted gas injection pressure does not exceed 10bar, so the method is a very promising technology.
The current air entrainment injection technology adopts the method that liquid fuel is injected into compressed air at the upstream of an electric control air nozzle through an electric control fuel injector, when an air valve of the electric control air nozzle is opened, the air tears and crushes the previously injected fuel, and the fuel is atomized into micro liquid to be sprayed together with the air. The fuel injector in the air entrainment injection system is responsible for measuring the quality of fuel, the air nozzle is responsible for atomizing liquid drops and injecting time, and the air entrainment injection technology separates the two requirements of accurately measuring the fuel injection quality and improving the atomization quality, so that the realization is more convenient. Generally, the injection strategy of the two nozzles is that fuel is injected firstly, and the air nozzle is opened after a period of time. It can be seen from the above that the liquid fuel injected first enters the chamber upstream of the nozzle, and within the time frame during which the nozzle is open, the fuel is substantially trapped by air in the early stages and is ejected from the gap, while almost all of the fuel is air and little liquid fuel is present in the late stages of the gas injection. The droplet size of the liquid particles is preferably smaller in the early stage and smaller in the later stage, from the viewpoint of the requirement of combustion for spray characteristics, so that the spray size larger in the early stage of the current air entrainment jet is disadvantageous in the uniformity of the spray and the later stage of combustion discharge.
